  "sound fixes for 4.19-rc5

   here comes a collection of various fixes, mostly for stable-tree
   or regression fixes.

   Two relatively high LOCs are about the (rather simple) conversion of
   uapi integer types in topology API, and a regression fix about HDMI
   hotplug notification on AMD HD-audio.  The rest are all small
   individual fixes like ASoC Intel Skylake race condition, minor
   uninitialized page leak in emu10k1 ioctl, Firewire audio error paths,
   and so on."
